After having some plane trouble, Justin Bieber sings his heart out behind the mic as he performs a free concert at Nokia Plaza L.A. Live in Los Angeles on Saturday afternoon (February 13).

The 15-year-old musician tweeted about his not-so-good travel day: “Been up since 5am trying to catch a flight to LA to make it to the bieber baby crawl with KIIS…bad travel day. Worst travel day ever- nothing more to say. That says it all.”

Justin finished off, “Rough day but thanks to @1027KIISFM and everyone who waited 4 me to land at La Live. Hit the kings game afterwards. Rough start- solid end.”
